Relationships among pain, anxiety, and depression in primary care.

Pain, anxiety, and depression are commonly seen in primary care patients and there is considerable evidence that these experiences are related. This study examined associations between symptoms of pain and symptoms and diagnoses of anxiety and depression in primary care patients. Results indicate that primary care patients who endorse symptoms of muscle pain, headache, or stomach pain are approximately 2.5-10 times more likely to screen positively for panic disorder, generalized anxiety disorder, or major depressive disorder. Endorsement of pain symptoms was also significantly associated with confirmed diagnoses of several of the anxiety disorders and/or major depression, with odds ratios ranging from approximately 3 to 9 for the diagnoses. Patients with an anxiety or depressive disorder also reported greater interference from pain. Similarly, patients endorsing pain symptoms reported lower mental health functioning and higher scores on severity measures of depression, social anxiety, and posttraumatic stress disorder. Mediation analyses indicated that depression mediated some, but not all of the relationships between anxiety and pain. Overall, these results reveal an association between reports of pain symptoms and not only depression, but also anxiety. An awareness of these relationships may be particularly important in primary care settings where a patient who presents with reports of pain may have an undiagnosed anxiety or depressive disorder.

Adherence to treatment among economically disadvantaged patients with panic disorder.

OBJECTIVE: The purpose of this study was to examine the feelings of disadvantaged patients about and experiences of treatment for anxiety disorders in primary care settings. METHODS: The patients had participated in the Collaborative Care for Anxiety and Panic study, which tested the effectiveness of an intervention to help primary care providers treat panic disorder. The treatment comprised cognitive behavioral therapy (CBT) combined with pharmacotherapy administered by primary care physicians with the expert advice of a psychiatrist. Post hoc semistructured interviews were conducted with 21 intervention participants who were classified according to adherence or nonadherence to treatment. The interview focused on reactions to CBT; reactions to the different features of the intervention, such as therapy sessions, demonstration videotapes, exercises, and a workbook; and comfort with the therapist. Two members of the research team independently coded, analyzed, and interpreted the data. RESULTS: Three themes emerged: information was empowering and reduced the sense of isolation experienced by participants, participants engaged in a dynamic and iterative personalized assessment of the intervention, and barriers to adherence were predominantly logistical. CONCLUSIONS: Results indicate that the extent to which patients chose to remain in treatment and follow treatment recommendations was rarely an all-or-nothing phenomenon. In a disadvantaged population such decisions seem to be influenced by the beliefs of the patient about what will and will not be effective in his or her individual case, an ongoing self-assessment of well-being, and the logistical barriers that come into play.
